A high altitude rum raisin apple butter cake, made with homemade apple butter. This cozy fall cake is moist, studded with plump raisins and flavored with dark spiced rum, and the fluffy buttercream is spiced with cinnamon, nutmeg and cloves. For a beautiful presentation, I decorated the cake with fresh apple slices, chopped walnuts, and star anise.

Why You’ll Love This Recipe
Cozy Fall Flavors. What could be better on a chilly fall day than warm flavors like spiced apple butter, brown sugar, rum and raisins in a delicious cake? This cake is sort of the apple version of a carrot cake, which is another of my favorites in the fall.
Easy to Make. This is a “whisk and bake” kind of cake, which is the easiest to make. You don’t need to cream the butter and sugar, simply whisk together the dry ingredients, whisk in the liquid ingredients and bake. This rum raisin apple butter cake is so moist and flavorful, and just delicious with the spiced vanilla buttercream.
Perfect for a Holiday. This would make a wonderful cake to serve for a Thanksgiving or Halloween celebration.
High Altitude Tested. I develop all the recipes on my site for Denver’s altitude of 5,280 feet, so mountain bakers can make my recipes with confidence.

Ingredients
Cake
- All-Purpose Flour. Creates a structured cake batter.
- Dark Brown Sugar. Adds sweetness, moisture, and a hint of molasses flavor.
- Baking Soda. Leavens the cake, making it rise.
- Coarse Kosher Salt. Balances the sweetness.
- Apple Butter. Adds flavor, moisture and spice. Try making your own homemade apple butter, or just buy a jar the next time you’re at the grocery store.
- Vegetable Oil. Adds moisture.
- Whole Milk. For moisture and richness.
- Spiced Rum. Adds flavor. Be sure to use a dark spiced rum, not a white rum. Although the alcohol bakes off, for an alcohol-free version, substitute the rum with water.
- Eggs. Adds richness and structure.
- Vanilla Extract. Flavor.
- Raisins. A delicious textural contrast to the soft cake.
Buttercream
- Butter. I use unsalted butter, but if you use salted, just omit the extra salt in the recipe.
- Powdered Sugar. Sweetens and thickens the buttercream.
- Meringue Powder. Adds stability and improves the texture.
- Spices. Salt, cinnamon, nutmeg, cloves and vanilla extract add the most wonderful flavor to complement the cake.
Instructions
Cake
- Preheat the oven to 350 F, and spray the bottoms of three 8-inch cake pans with non-stick baking spray.
- In a large bowl, whisk together the flour, baking soda and salt.
- In a separate bowl, whisk together the brown sugar, apple butter, oil, milk, rum, eggs and vanilla.
- Add the dry ingredients, and whisk just until combined, then fold in the raisins.
- Divide the batter between the pans. Bake on the center oven rack for about 20-22 minutes, until a cake tester or toothpick comes out clean.
- Set the pans on a cooling rack, cover loosely with a clean kitchen towel, and cool completely.
Buttercream
- In the bowl of your stand mixer fitted with the whisk attachment, beat the butter for 1 minute. With the mixer on low, add the powdered sugar, meringue powder, salt, spices and vanilla and mix to combine.
- Beat for 4-5 minutes on medium high speed until very light and fluffy. Only add the milk if needed for desired consistency.
- Fill, stack and frost the cooled cakes with the buttercream.

Frequently Asked Questions
How should I store the leftover cake?
Leftover rum raisin apple butter cake should be stored in an airtight container or cake carrier at room temperature for up to 3 days.
Can I make this recipe with the rum or the raisins?
Yes, for just an apple butter cake without alcohol or raisins, simply leave out the raisins and replace the rum with water.
How should I adjust the recipe for a 6-inch cake?
For a three layer 6-inch cake, you can cut the recipe in half. The cake layers will bake for about the same time as the 8-inch layers.
Will the apple slices on top turn brown?
Yes, something to keep in mind if decorating the cake as shown in today’s photos is that fresh apple slices do turn brown when exposed to air. To decorate your cake as I did, wait until you’re ready to serve the cake. Then cut the apples and lightly brush the apple slices with lemon juice. Arrange the apples, chopped walnuts and star anise on the cake for a lovely presentation. You will need to remove everything from on top of the cake before cutting it, and of course, no one will want to eat the star anise, although it makes a beautiful decoration.

This cake is delicious, but I am curious…your photos look like a 6″ cake, yet the recipe says 8″ cake pans. Just wondering if I would need to make 6″ cakes to get this look.
You’re correct, I test my recipes multiple times in different sizes of pans, and the photographed cake is half the recipe baked in 6 inch pans.
